摘要：
The friction coefficient of elastic sliding bearings is velocity-dependence. Since this dependence is particularly strong in the low velocity range, it is important to consider this dependence when designing structures for forces that result in low-response speeds, such as wind forces. However, conventional design methods do not consider the effect of velocity dependence. In this paper, an equation for the velocity dependence of the sliding friction coefficient at low velocities is derived from experiments. An analytical model to simulate this dependence is proposed to enable more accurate calculation of the restoring force characteristics of the elastic sliding bearings. © 2024 Architectural Institute of Japan.
